I have a RoadRunner 68, I'd like to put in a dual quad set up. Will an earlier 59-62 Casting #1827899 Intake manifiold fit a stock Mopar 383 hp engine with 516 heads?
Does anyone know if there is a difference between the external casting numbers and dates for 383 or 440 engine blocks between Dodge engines and Plymouth engines. I realize there are internal difference but I am curious about the external casting numbers and dates between the two.
